Standard C++ Library Class Reference

r value of type X&

t value of type T

Requirements for Output Iterators

The following expressions must be valid for output iterators:

X(a) copy constructor, a == X(a).

X u(a) copy constructor, u == a

X u = a assignment, u == a

*a = t result is not used

++r returns X&

r++ return value convertable to const X&

*r++ = t result is not used

The only valid use for the operator * is on the left hand side of the assignment statement.

Algorithms using output iterators should be single pass algorithms. That is, they should not pass

through the same iterator twice.
